    Abstract: A compression device includes: an electrochemical cell that includes an anode and a cathode that sandwich an electrolyte membrane; a voltage application unit that applies a voltage between the anode and the cathode; and a metal plate that is exposed to compressed hydrogen generated at the cathode and that is resistant to hydrogen embrittlement. The metal plate includes a first terminal connected to the voltage application unit. The first terminal is directly connected to a second terminal that has a lower resistance than the first terminal. The second terminal is directly connected to the voltage application unit, and the first terminal is connected to the voltage application unit via the second terminal.

    Abstract: There are provided an electrolyzer gasket, which can accommodate and hold a separator inside an electrolyzer by a simple handling, can more surely prevent leakage of an electrolyte and an electrolytically generated gas from the inside of the electrolyzer, can keep the separator in such a state that the separator is held at a position that is in contact with one of electrodes and is located along the electrode and therefore can suppress damage of the separator and makes it possible to use the separator stably for a long period of time, and an electrolyzer. An electrolyzer gasket including a picture-frame-shaped thin-plate-like frame having a first surface being in contact with an anode metal frame and a second surface being in contact with a cathode metal frame, wherein the gasket has a structure in which a notch having a difference in level of approximately the same thickness as the thickness of the separator, the notch obtained by thinly scraping off, in a uniform thickness, a region including the edge on the anode chamber side or the cathode chamber side, is formed on any one of the first surface and the second surface, and the edge part of the separator is accommodated and held in the notch, and an electrolyzer using the electrolyzer gasket.

    Abstract: An electrochemical hydrogen pump includes at least one hydrogen pump unit including an electrolyte membrane, an anode, a cathode, an anode separator, and a cathode separator; an anode end plate disposed on the anode separator positioned in a first end in a stacking direction; a cathode end plate disposed on the cathode separator positioned in a second end in the stacking direction; a fixing member that prevents members from the anode end plate to the anode separator positioned in the first end from moving in the stacking direction; a gas flow channel through which hydrogen generated in the cathode is supplied to a space disposed between the anode end plate and the anode separator positioned in the first end; and a pressure transmitting member that is disposed in the space and transmits a pressure from the anode separator positioned in the first end to the anode end plate.
